I do portraits and weddings for a lot of people of color. One thing to watch out for is dodging the face too much, because you will be (trust me on this) accused of trying to make them look too white. On the other hand, you do need to light it enough to see the details. That's why the proper light in the first place really helps.

This is difficult, because obviously, she does have a much darker face than her legs/arms... my guess is a suntan as well as just normal skin coloration.

It gets even more tough when you have really light skinned people, mixed with very dark skinned people. Just follow my rule. Edit it ever so lightly, then back it off a bit more than you think you should.

Nothing is more insulting to a dark skinned person, than trying to make the face too light, even making them look like a light skinned
African American. They have issues between light and dark skin within their own community. (again, I know, been there, thought I was doing a good thing, not because it was lighter skin, but because you could see her face more.......yeah, not a happy camper) My old business partner, and one of my assistants are dark skinned, and they have taught me a lot about the culture, and what is acceptable.

Just do less than you think you should, then back if off a little from there, and everyone will be happy, including you.
